HOLDFAST FOR PORTABLE SHOWERS, SHAMPOO-SPRINKLERS, 80G- SPECIFICATION forming part Of Letters Paten N 7'71,306, dated October 4, 1904. Application filed June 22, 1903. Serial No. 162,490. (No model.)

To a, whom it may concern:

Be it known that I, EDGAR F. GREGG, a citizen of the United States, residing at Thornburg, in the county of Allegheny and State of Pennsylvania, have invented or discovered new and useful Improvements in Holdfasts for Portable Showers, Shampoo-Sprinklers, &c., of which the following is a specification.

In the accompanying drawings, which make IO part of this specification, Figure I is a front elevation of a water-fixture commonly employed in bath tubs, my invention being shown in section and applied to the outlet of the fixture; Fig. II, a view, half in side ele- I5 vation and half in vertical section, showing the clamping-ring which I use; Fig. III, a view similar in character to Fig. II, showing the guard or protective ring; Fig. IV, a like view showing the body portion of my invention, and Fig. V a like view showing the elastic diaphragm.

My invention relates to hose or pipe couplings, and more particularly to that species of coupling known as a holdfast, whereby a 5 hose leading to a certain attachment for bathtubs or to a shampooing or spraying head may be readily attached to or detached from the usual water-fixtures of a bath-tub or washbowl or to a faucet or tube. Its object is to provide 3 a holdfast which can be made at a comparatively low cost and is so constructed that in case a break occurs it may be quickly and cheaply repaired without a sacrifice of the Whole holdfast.

The water-fixture by the numeral 1.

2 and 3 indicate the levers by which the hot and cold water is turned on and off, and 4 represents the outlet pipe or nozzle of the 4 fixtures.

as a whole is designated 5 is the metal body portion of the holdfast,

and consists of a lower tubular part 6 and an upper flaring or bell shaped part 7 The part 6 is provided with ribs or corrugations 8, to which is attached the hose 9, leading to any desired head-such, for example, as are used for showers, shampooing, sprinkling, or spraying. The upper end of the body 5 is provided with an endless 10, and the threads 11.

12 is the clamping-ring, having on its lower side an endless or annular groove 13, similar to the groove 10. The ring 12 has an annular flange 14., threaded interiorly, so as to cooperate with the exterior threads 11. The ring 12 is provided exteriorly with an annular groove 15, in which is seated the elastic guard or protective ring 16, made, preferably, of rubber.

17 is an elastic diaphragm having a permanent circumferential head or rib 18, whose under portion 19 fits the groove 10 and upper portion 20 the groove 13. The intermediate portion 21 of the diaphragm is convex, and its central portion has an opening 22, formed by the tubular downwardly-extending portion 23. The tubular portion 23 of the diaphragm is of such a diameter that when it is pushed over the nozzle 4 it will fit the same suificiently tight to keep the pressure of the water from forcing the holdfast off the nozzle. By making the hole 22 flanged, so as to form the tube 23, the diaphragm is not so liable to be torn.

In assembling the parts of my holdfast I screw the clamping-ring 12 upon the body 5, the diaphragm 17 being clamped between the ring and body. The bead 18 is seated in the grooves 10 and 13, which prevent the diaphragm from being pulled ofi from its seat. It will be found difiicult to force the diaphragm through the ring even before the ring is screwed on the threads l1. The portion 20 of the bead and the groove 13 are preferably larger than the portion 19 of the bead and the groove 10.

The ring 16 protects the enamel of the bathor annular groove periphery at this end has the tub or other fixture from injury in case the holdfast should fall upon it.

The only part of my holdfast that will need to be replaced is the rubber diaphragm l7, and when this becomes necessary the ring 12 can be easily screwed off and a new diaphragm put on.

I do not desire to be limited to the precise form and size of the parts shown, as many opposite the groove in the body portion, and a yielding diaphragm having a permanent head in the two said grooves, the clamping-ring causing the bead to be retained by the grooves and to form a Water-tight joint between the ring and the body portion.

Signed at Pittsburg this 19th day of June,

EDGAR F. GREGG. Witnesses:
